TOWER-PTFE ATTACHMENT FOR HOOK-ANDd-LADDER TRUCKS.

SLECIFICATION formingpart of Letters Patent No. 339,272, dated April 6, 1886.

Application filed August 13, 1885.

HOOkand-Ladder Trucks; and I hereby declare the following t-o be a full, clear, and exact description thereof. reference being had to the accompanying drawings, which form a part of this specification.

This invention relates to improvements in a certain tower-pipe attachment to trucks invented by me, for which Letters Patent No. 297,919 were granted to myself and assignees on April 29, 1884. v

These improvements are twofold, and consist, rst,in improved means for raising and lowering the tower-pipe in connection with the platform to which the same is attached; and, secondly, in improved means for bracing and steadying said pipe, all as hereinafter particularly set forth and described.

In the accompanying drawings, Figure 1 represents a side elevation of the rear por tion of the truck, together with my improved attachment applied thereto. Fig. 2 is a front elevation of said attachment. Fig. 3 is an elevation of the towerpipe, showing my improved means for bracing the same. Fig. 4 is a view of the brace on a larger scale.

Similar letters ot' reference indicate the same parts in all said several gures.

A is the rear portion of a hoolrand-ladder truck of ordinary construction.

B is a bracket of peculiar construction, in which aplatform, C, is pivoted, which holds the tower-pipe, and to which my present improvements are applied. This bracket is attached to the frame or body of the truck by means of a rectangular frame, c, which is integral with'said bracket.

In the patent above referred to the devices for raising and lowering the pipe D were connected with the platform C, raising and lowering the latter and the said pipe along with it; but in this improvement the raising and lowering devices are connected directly with said pipes, and are simpler in construction and more easily operated, besides being better adapted for preventing damage to the Serial No. 174 354. (No model.)

pipe in raising and lowering it. The pipe D is connected to the platform O, as in the former case, and the means for adjusting the pipe laterally, consisting of a screw-threaded rod, E, working in apivoted projection, e, attached to the pipe, are similar.

My improved appliances for raising and lowering the pipe are as follows: F is a rope or chain provided with a hook, b, at its outer end, which said hook engages with an eye, e, attached to the pipe D. The other or inner end of this rope, after being passed over a pulley, d, fixed upon a shaft, G, having bearings in the side of the bracket, is wound around a roller, f, which is also journaled in the sides ofthe bracket. Upon one end of the journals, outside ofthe bracket, is a crank, H, by which said roller is turned; or a gearwheel, l, may be fitted on said journal to mesh with a pinion, g, journaled in the sides of the bracket and having the crank fitted on its shaft, so as to give a slower motion to said roller. By this means the pipe may be raised or lowered into any desired position to play with best effect, and is held in that position by means of a dog or pawl, h, which engages with the teeth of the wheel l,

The paits which do not form part of this invention, and which it is not deemed neces` sary to describe at length, are as follows: J are the rear wheels of the truck. G is the steering apparatus, which may be of ordinary construction. H is an adjustable brake for holding the wheel. I/ are braces for holding the rear of the truck in the position desired, and which are pivoted at their upper ends to suitable eyes, i, so that they can be swung around and packed, along with the ladders, in the body of the truck when not in use. J is a rod, which is also pivoted to an eye in similar manner, and is for the purpose of aiding in supporting the end of the platform C, which rests upon it. K is a reel to which one end of a cord, K, for raising or lowering the nozzle (not shown) is attached.

In my second improvement the truss or brace is made detachable, and is constructed as follows: Braces or stays L of novel construction, hereinafter particularly described, are inserted, one at each coupling le, except on the roo rst length D, which is attached to the platform. On said length D is an eye, l, to receive a hook on the end of a cord, m, and a similar eye, Z', is attached to the top length of pipe, which receives another hook on the other end of the said cord. The ends of said cord m are attachedby said hooks to the eyes Z and Z", and the intermediate portions l[hereof are attached to said braces.

The braces L are each constructed as follows: n is a base-piece, which fits over a portion of the towerpipe, and has a screw-pin, o, extending outwardly. p is a central piece through which said pin passes, and which may be adjusted upon said pin 0 by means of a screw-nut, q. r is a separate piece swiveled upon the piece p, and s is a short barswiveled on the piece r and provided with perforations or eyes t at its two ends to receive the cord m, and fastened by a screw-nut, u, which ts onto a screw, r', extending from the piece r. By

means of this construction the brace-truss may be attached at pleasure, and also tightened to any desired degree, and when attached is capable of adjusting itself to the different movements or positions of thc cord my.

I may state that the platform C is pivoted to the brace B, and when let down the pipe assumes the position shown by the dotted lines y in Fig. 1, and rests against abar, w, extend- :ing downward from the body of the truck.

Having thus described my improvements, what I claim as my invention isl. In combination with the truck A, bracket B, and pipe D, attached to the platform C, the roller f, crank H, pulley d, and rope or chain F, connected to said pipe, all as shown and described.

2. In combination with the truck A, bracket B, and platform C, the pipe D, attached to said platform, roller f, crank H, pulley d, rope or chain F, and gear-wheels I and g, as shown and described.

8. The brace or braces L, each composed of the pieces n op q r s, connected with the cord 45 m and pipe, as shown and described.
